GSN

A collaborative project.The Global Seismographic Network (GSN) is a
155 stations collaborative project that provides realtime data through the
IRIS DMC. The GSN is a cooperative partnership between IRIS and the
U.S. Geological Survey (USGS).

IRIS, with funding from the National Science Foundation, provides overall
management and oversight for the GSN. IRIS provides a subaward to
Project IDA (International Deployment of Accelerometers) at the
University of California, San Diego, to operate 41 stations of the network.
Another ~100 stations are operated by the USGS. The remaining 12 stations are
part of an affiliated network meeting the design goals of the GSN, but
operated outside the NSF/USGS funding.
